Fertilizer Mix Optimizer

Target Analysis

Nitrogen (N)

Phosphate (P₂O₅)

Potash (K₂O)

Batch size

Leave blank or zero to get percentages only.

Ingredients

Enter up to five fertilizer sources (N, P₂O₅, K₂O). Use fillers (0-0-0) if needed.

📖 How to Use

Enter the desired N‑P‑K analysis, then add fertilizer sources (e.g., urea 46-0-0, DAP 18-46-0, MOP 0-0-60). The solver finds the mix that matches the target or tells you if the target is impossible with the chosen ingredients.

🧮 Formula Reference

Σ(ingredient fraction × nutrient%) = target nutrient%
Σ ingredient fractions = 1 (or batch total)
Solve for ingredient fractions using simultaneous equations.
